They are very sweet and full of water, and many people grow them. Because growing strawberries offers great economic benefits, and the market price of strawberries is relatively high among fruits, the income can be quite considerable if they are grown properly. But many fruit growers find that strawberries often get sick during cultivation, so what are the common strawberry diseases? How should they be controlled? Let's take a look below!</p> <p></p> <p><strong>1. Leaf spot</strong></p> <p>Disease characteristics: Leaf spot can occur on any organ of the strawberry plant. It mainly harms the leaves. After the leaves are infected, darker spots appear on the surface, and the spots gradually expand to form patches of varying sizes with darker edges. The middle of the patch is white and develops many small black dots.</p> <p>Control methods: Promptly remove the infected parts, such as diseased leaves and diseased fruit, and dispose of them far away from the orchard. After infection, chlorothalonil wettable powder can be sprayed for control, once every 7-10 days.</p> <p></p> <p><strong>2. Powdery mildew</strong></p> <p>Disease characteristics: The main site of powdery mildew infection is also the leaves, and it occasionally harms other organs of the plant as well. After the leaves are infected, white mold appears, and the mold layer takes on the shape of a spoon. After flowers are infected, the disease occurs on the buds and petals, with darker color, affecting flowering; in severe cases, the plant cannot bloom, the fruit develops poorly, expansion is hindered, fruit quality is reduced, and it loses commercial value.</p> <p>Control methods: Strengthen orchard management. After infection, spray Bordeaux mixture and lime sulfur mixture around the plants. At harvest, cut off all the leaves, then spray the whole orchard with solutions such as thiophanate-methyl for control.</p> <p></p> <p><strong>3. Gray mold</strong></p> <p>Disease characteristics: The peak period of gray mold is during the plant's flowering stage. Like leaf spot, it harms most organs of the plant. It mainly occurs on the fruit. After the fruit is infected, many brown spots appear, and the spots slowly expand and then join together to form a large patch, causing the fruit to rot and soften, with rotten and fallen fruit, greatly affecting yield.</p> <p>Control methods: Carefully observe the plant's growth progress. Before the flowering stage arrives, spray agents such as carbendazim wettable powder for prevention. Manage the orchard well, drain and irrigate in a timely manner, and improve orchard ventilation.</p> <p></p> <p><strong>4. Root rot</strong></p> <p>Disease characteristics: Root rot mainly occurs on the leaves. When the leaves are infected, it mainly starts from the lower part and then gradually spreads to the upper leaves, with the leaf edges becoming darker. After the leaves are infected, they slowly wilt and eventually die. As the leaves wither, the plant also slowly changes color and eventually rots, affecting nutrient absorption and transport and causing great harm to plant growth.</p> <p>Control methods: When transplanting strawberries, spray asparagus green powder on the beds. After spraying, cover with an appropriate amount of soil, then transplant. This reduces or even eliminates pathogens in the soil, reducing pathogens and lowering the disease incidence.</p> <p></p> <p>The four diseases above are relatively common in strawberry cultivation and can have a great impact on plant growth, not only reducing yield but, in severe cases, leading to total crop loss. Therefore, when planting, we must pay attention to strengthening orchard management and promptly remove fallen leaves and fruit and diseased leaves and fruit from the orchard. Prevent re-infection. That is all for today's introduction. This article is for reference only, and we hope it is helpful to everyone.</p>
